Abuse of Traffic Controlling Devices

Stop Signs as Speed Controlling Devices

A large proportion of the stop signs erected by local governments are
illegal and in violation of state traffic regulations. They know that
people don't stop for them since the intention is to use the signs as
speed control devices. This proliferation of stop signs merely
increases the number of motorists who can be cited for failing to stop
when there is no reason to.

The Short Yellow Trap

A trick that works by first setting the yellow lights to four seconds
on most of the municipalities traffic lights. Then, on a few
well-chosen intersections, the city sets the yellow light to three
seconds and stations a police officer just down the street from the
light, ready to give you a ticket.
